Anne Lundberg was named head of institutional distribution at Thornburg Investment Management.
It is a new position, a spokeswoman said. Ms. Lundberg will be based in Chicago and will oversee business development, client services and institutional partnerships in North America.
She reports to Carter Sims, managing director and head of global distribution.
Ms. Lundberg was previously co-head of institutional distribution and head of North America consultant relations at GAM.
